L3DGEWorld 2.3, a product of the L3DGE project, is a data visualisation tool based on the OpenArena derivative of the Quake III Arena game engine, being used in the monitoring and control of networks. This technical report briefly describes some previously undocumented functionality of L3DGEWorld 2.3. It will describe how we have implemented a multi-level hierarchy, which could be used to represent networks, hosts and flows, and the room re-use technique used to achieve this within the limitations of the engine.
